SPECIFICATION forming part of Letters Patent No. 766,499, dated August 2, 1904.

Application filed February 5, 1904. Serial No. 192,129. (No model.)

To all whom it 771/(LZ/ concern.-

Be it known that I, WILsoN L. GooDRIon, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in I Iorseshoe-Calks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute parts of this specification, and represent, in-- Figure 1, a perspective view of a horseshoe having calks constructed in accordance with my invention applied thereto; Fig. 2, a perspective view of one of the calks detached; Fig. 3, a broken sectional view of a portion of the shoe, showing one of my improved calks connected therewith, the calk being shown in side elevation.

This invention relates to an improvement in horseshoe-calks, and particularly to that class which are provided with threaded shanks for attachment to or removal from horseshoes provided with threaded openings to receive the shanks, the object of the invention being a construction which will remain sharp and which will not clog; and the invention consists in the construction as hereinafter described, and particularly recited in the claim.

As herein shown, the calk consists of a body 2 and a threaded shank 3, the shank being adapted to enter threaded holes at, formed at the heels and toe of a horseshoe 5 of usual construction, the inner end of the body being substantially square, forming shoulders 6,

adapted to bear upon the outer face of the shoe. The outer end of the calk is of N or Z shape-that is, comprises sides 7 and 8, the end of one side being connected to the diagonally opposite end of the other side by a diagonal web 9. The metal from the edge of the web 9 merges into the upper end of the body in a curved line, forming a curved channel 10 on each side, gradually increasing in depth from the upper end of the calk to the edges. By forming the outer end of the calk of N or Z shape and curving the inner surfaces of the channels on opposite sides the possibility of clogging with mud or snow is avoided, as pressure on the outer end will force material in the channels out instead of causing them to pack therein. These calks, like others of the class, may be readily removed with a wrench and sharpened or replaced by new ones when the calks become worn.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

A horseshoe-calk having two sides connected by a diagonal web forming two V-shaped channels increasing in depth from the upper end of the calk to the edges, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
